How to breed dairy cows at the right time? Mastering the best breeding time is key

Because cows have a short estrus duration and ovulate quickly, when using assisted mating or artificial insemination, mastering the right timing for breeding (insemination) is very important for improving the conception rate of cows. Now let us take a look at the timing and methods for breeding cattle!

For growing heifers that have reached 15 to 18 months of age or a body weight of 350 kg, and for production cows 2 to 3 months after calving, timely breeding can improve the reproductive rate and yield greater economic returns.

First, pay attention to observing the cow's estrus. During estrus, the cow appears excited, behaves restlessly, often mounts other cows, and also accepts mounting by other cows, with transparent mucus flowing from the vulva.

Second, inform the breeding technician of the exact time of estrus (ovulation occurs 10 to 12 h after the end of estrus, sperm survive in the reproductive tract for 24 h, and the egg survives for 6 to 12 h), which can effectively improve the conception rate of artificial insemination. About 24 h from the beginning of estrus, artificial insemination is carried out using the method of holding the cervix by hand. Jin Qiao'e
